WebApr 5, 2024 · 1 Answer. Sorted by: 1. Yes, they are saturable, because they have a finite number of 'binding sites', depending on the particular example you are looking at. Then, once they join the substrate to be transported, they need to release it at the other side of the membrane, which takes time (in very short time scales, but time nevertheless). WebThe calcium channel proteins are mostly found in skeletal muscles, bones (osteoblasts), brain, peripheral nervous system, spines, neurons, etc. The main function of calcium channel proteins is to transport calcium ions to their destinations. It releases calcium ions and stimulates signal transduction procedures.

Membrane carrier proteins differ from membrane channel proteins by which of the following characteristics? a) Carrier proteins are glycoproteins, while channel proteins are lipoproteins. b) Carrier proteins transport molecules down their electrochemical … WebApr 28, 2024 · Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient.
WebActive transport of small molecular-size material uses integral proteins in the cell membrane to move the material—these proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action. In secondary transport, energy from primary transport can be used to move another ...
WebAn autoclave is a device used to sterilize medical instruments. It is essentially a pressure cooker that heats the instruments in water under high pressure. This ensures that the sterilization process occurs at temperatures greater than the normal boiling point of water. Explain why the autoclave produces such high temperatures.
